chexit

A tool to check the actual IPv4 and IPv6 exit address of all Tor exit nodes.

Description

chexit is a small Rust program that utilizes arti in order to obtain all actual exit addresses. It fills a gap in the regard that it is the only(?) tool that also collects IPv6 exit addresses alongside the IPv4 ones. Originally it was written in the hope to eventually support IPv6 for check.torproject.org. It is a highly efficient tool that can gather ≈ 99% of all exit addresses within 4 minutes (maybe even less).

Usage

$ RUST_LOG=info chexit > exit_addresses

Implementation Details

chexit works as follows:

  1. Bootstrap the consensus
  2. Spawn as many asynchronous tasks as there are exit nodes in the consensus
    1. Create a channel to a guard node
    2. Create a two hop circuit to the exit node
    3. Create an IPv4 and IPv6 stream to ip.cve.cx
    4. Perform an HTTP GET and parse the result
  3. Wait 4 minutes for all tasks to finish
  4. Collect the results, write them to stdout
